Answer:
A ruler.
Explanation:
Just measure height, length and width and multiply each.
Let me think about this........ correct me if I am wrong.......
Laws of thermodynamics
1) Energy cannot be created nor destroyed. It is transferred.
2) All spontaneous reactions will increased the entropy of the universe (More disorder)
3) The entropy of the crystal lattice structure at 0 K is zero
PE(coal) --> Steam(K.E) ................ This will increase entropy and also conversion of energy. So BOTH LAWS is my final answer.
Wait...... I would like to use a lifelines...... I want to phone my Physical chem professor.
*Ring Ring.........*
Me: Hello, I wanted to make sure if I got the correct answer.
Chem prof: You dont need my help, since you got the right answer.
Me: WOOT!!!!!!!
Answer:
stagnant current
Explanation:
stagnant current because eit is
Answer:
(a) 0.42 m
(b) 20.16 N/m
(c) - 0.42 m
(d) - 0.21 m
(e) 17.3 s
Solution:
As per the question:
Mass, m = 0.56 kg
x(t) = (0.42 m)cos[cos(6 rad/s)t]
Now,
The general eqn is:
where
A = Amplitude
= angular frequency
t = time
Now, on comparing the given eqn with the general eqn:
(a) The amplitude of oscillation:
A = 0.42 m
(b) Spring constant k is given by:
Thus
(c) Position after one half period:
(d) After one third of the period:
(e) Time taken to get at x = - 0.10 m:
t = 17.3 s
Acceleration is 0, speed is constant, velocity is always changing because if you are running in a circle the direction you are facing always changes
